Command Line Syntax

GDS_Extents is command line driven. The syntax is described below:

gds_extents input_file output_file top_struct input_layer_set [options]

where 

  gds_extents        path and filename of the executable "gds_extents"

  input_file         is the input GDSII file to be analyzed. Use path
                     if the file is not located in the current directory

  output_file        is the base output filename - gds_extents can generate
                     multiple output files (if more than once cell is
                     specified) so this base name is used along with additional
                     characters to provide a unique output file name.

  top_struct         normally the top level structure of the input file. However
                     a use may specify any structure in the input file as the
                     starting point. If you do not know the name of the top
                     level structure use the "=" character to indicate you
                     want the program to determine the top level structure.

  input_layer_set    use the "=" character to indicate that all layer data should
                     be used when computing cell extents. If you want to use
                     only specific layers then list them using a comma delimited
                     list such as 1,2,3

options

  -cell_extents <cell_list> 

                     where <cell_list> is a comma delimited list of cell
                     names or @<filename> where filename is a text file
                     containing one cell name per line

  -gds               create gds file output instead of an ascii output

  -text              include TEXT to extent calculation. If this option is not
                     present then by default any text insertions are ignored
                     when computing extents.

  -window:x,y,X,Y    analyze windowed data only
